A device to produce electricity using the flowing water or the lashing sea waves. It is a novel method of underwater turbine comprising of a central axis 2 with which the popping up drag door pans 3 are attached laterally in multiples at equal distance, a set of gears which transfer the force from the central axis 2 to the generator 6, a floating system that helps the whole instrument to float in the water column and a metal stand 1 which holds all the components. The popping up drag door/s 4 of the popping up drag door pan 3 is open able only one side. The popping up drag door/s of two opposite popping up drag door pans 3 are open able towards the opposite directions. While the water flowing or lashing over the turbine, the popping up drag door/s 4 of one popping up drag door pan 3 is forcefully opened by the water force and the water passes to the other side through the gaps of the opened door/s. Simultaneously, the popping up drag door/s 4 of the opposite popping up drag door pan 3 are forcefully closed by the water force, the popping up drag door pan 3 is pushed back and in turn the central axis 2 is rotated. |
